Palimpsestes urbains - Le Divan Fumoir Bohémien David Rumsey, fameux et généreux collectionneur américain de cartes anciennes, met à disposition du public sur son site un fabuleux outil pour qui aime à se promener en imagination dans les villes. Il permet de surimposer des cartes anciennes aux cartes contemporaines fournies par Google Maps en faisant affleurer le maillage et le bâti actuels par un jeu de transparences (réglette graduée en haut à droite) . Imaginer les cheminements dans Paris sans les percées haussmanniennes ne réclamera plus comme auparavant un énorme effort de défamiliarisation grâce à ceci. Et vous pourrez de la même manière voyager dans : - le Londres victorien - le New York de 1852 - le Berlin de 1860 - la Rome antique à travers un plan établi en 1830 - le Tokyo (Edo) de 1680 et bien d'autres villes à parcourir en compagnie de vos fantômes préférés.

Jay Melosh, and Gareth Collins Welcome to the Earth Impact Effects Program: an easy-to-use, interactive web site for estimating the regional environmental consequences of an impact on Earth. This program will estimate the ejecta distribution, ground shaking, atmospheric blast wave, and thermal effects of an impact as well as the size of the crater produced. Please enter values in the boxes below to describe your impact event of choice and your distance away. Tell me more...

Effects Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. " Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time. " - Intergovernmental Panel on Climate Change Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gasses produced by human activities. According to the IPCC, the extent of climate change effects on individual regions will vary over time and with the ability of different societal and environmental systems to mitigate or adapt to change. 3Ibid. 4Ibid. 5Ibid. 6Ibid.

Geology (faults, landslides, etc) Where can I find information on the faults and the geology of my area? Instruments and networks The Canadian National Earthquake Database What do the acronyms stand for in the list of Canadian earthquakes? Seismic Hazard and Earthquake Engineering Facing Earthquakes Seismologists What is an "earthquake"? An earthquake occurs when rocks break and slip along a fault in the earth. What causes earthquakes? Earthquakes are caused by the slow deformation of the outer, brittle portions of "tectonic plates", the earth's outermost layer of crust and upper mantle. How do earthquakes cause damage? Most earthquake damage is caused by ground shaking. Does the earth open up during an earthquake? No! Where do earthquakes occur? Can earthquakes be predicted?
